I think it would be a great challenge to try and capture the dynamics and motion of a (break)street dancer(s) in action. Do not know where or when as I have not done any research yet but I saw bits from sketchbook of Marco Nelor (look him up - the guy's mean) once and I would like to try.
I am not dead set on the street-dancers, though. Any would do. I am just really keen on taking part in this!
